Search google (or better, rimfirecentral.com) for P22's with cracked slides..you'll find a LOT of 'em because of the low quality metal used. You'll find plenty of people complaining about jamming, and sending brass into the shooters face.
On the flip, you don't find much in terms of complaints for the Neos...it is a very reliable piece. I've had mine for a few days short of one month, and have already bought several accessories. I'm right at 1,100 rounds fired so far. It was cleaned once between having all those rounds fired. Never had a jam, misfeed, or any other problem.
Here's my neos....
Factory U22 Neos INOX with 6" barrel.
Accessories include a 4.5" Inox barrel and BSA red dot (for fiance), spare Inox slide assembly, and three additional factory magazines for a total of five. I also ordered a few basic spare parts just in case (recoil springs, magazine parts, etc.) to keep the gun functioning. I'm not anticipating any failures, as this pistol seems pretty well made, but I plan to shoot at LEAST 15,000 rounds through it this year and want to be ready for anything. With that much use, ANY firearm should have it's recoil spring replaced as least once to help save some stress on the slide and frame.
I just need a better case to hold it all!
